Well, for one, they are appealing to the lies about the Ossuary of James. Whatever researchers think this is credible, presume the Ossuary of James, one of the most pathetic hoaxes in archaeological history, is actually true.
The inscription on the Ossuary of James was scratched THROUGH the patina, proving that the Ossuary was old, but the inscription is new. This discovery, with an empty space that the authors presume to be where the Ossuary of James was, lacks patina altogether on all but one ossuary.
Oh, wait... I forgot... a lot of folks fell for the Ossuary of James hoax because it was only anti-Catholic. Defending Christ would require eating too much crow...
Now, now, let's keep this ecumenical. (can't believe I said that, can you;-)) We have a common foe here.
